Ulla’s effective blinking alert, developed by the US Navy, ensures you’ll always notice Ulla no matter how busy or distracted.
A high-precision accelerometer always knows when you take a drink. So Ulla knows only to blink when you forget to hydrate regularly.
Ulla reminds you throughout the day to hydrate every 40 minutes – but only if you forget to drink. Good drinking habits, no blinking – simple.
Ulla’s designed to fit easily on any bottle, regardless of size or material, with its special silicone mounting band.
Ulla wakes up when you enter the room in the morning, and goes quietly to sleep when you turn the lights off for the night.
The easily replaceable CR2032 button cell battery lasts up to six months.
I love this little thing. Has helped me drink more and yes I feel better. I drink 3 times more now than I ever did.
